Various types of conventional elevating devices for furniture, electrical equipment, etc. are available.For example, a simple device is one in which a screw shaft is screwed from below to a nut fixed to the bottom plate of furniture, etc.
There is an adjuster that can adjust the vertical height by rotating the screw shaft, but in order to rotate the screw shaft, the nut fixed to the screw shaft must be adjusted with a spanner or the like. The adjustment had to be made by rotating around the screw shaft, which was a time-consuming operation, especially when there was no space between the bottom plate and the floor to put your hand in. In addition, in the 1980s, the height of the elevating body could be adjusted using a rotating shaft from the side.
As disclosed in Publication No. 77446, a screw shaft with a bevel gear fixed to its upper end is rotatably mounted in the main body, and a hollow elevating body having a nut-like member fixed to its upper end is screwed onto the screw shaft. A rotary operation shaft that meshes with the bevel gear appears on the side of the main body, and a rotary operation tool such as a screwdriver is fitted into a rotary operation section provided at the outer end of the rotary operation shaft and rotated. A device is disclosed in which the height can be adjusted by rotating the screw shaft at a fixed position and moving the elevating body screwed onto the screw shaft up and down. Since the structure is such that the screw shaft is always hung vertically in a fixed position, it is impossible to set the height between the mounting seat at the upper end of the main body and the floor contact surface of the lower end of the elevating body to be smaller than the length of the screw shaft. As a result, the overall height of the device becomes large and bulky, and when it is installed on the bottom plate of furniture, the distance between the bottom plate and the floor surface inevitably becomes wide, which causes problems in appearance. .

In view of the above-mentioned situation, the present invention aims to solve the problem by minimizing the height of the main body of the device and controlling the height adjustment even though the stroke length that allows vertical height adjustment can be set long. The object of the present invention is to provide a simple, small and lightweight height adjustment device for furniture, electrical equipment, etc.

According to the height adjustment device for furniture, electrical equipment, etc. of the present invention as described above, the drive has a mounting part that can be fixed to the lower part of the furniture, electrical equipment, etc., and has an opening vertically penetrating in the center part. A rotary wheel with a screw hole formed in the center and a bevel gear formed on the outer periphery is installed inside the main body so as to be rotatable in a fixed position in a horizontal plane, and a bevel gear integrally connected to the drive shaft is attached to the rotary wheel. A fitting part capable of connecting the operating jig formed at the end of the drive shaft when meshed with the bevel gear is made to appear on the side and is internally installed so that it can be rotated in a fixed position, and a grounding part is provided at the lower end. A lifting screw shaft connected to the drive body and having a vertical groove over substantially the entire length of the upper and lower parts of the drive body is inserted into the opening of the drive main body and is screwed into the screw hole of the rotating wheel, and the vertical groove is provided to protrude into the opening. Since it is slidably fitted into the protrusion, simply by fitting and connecting an operating jig such as a screwdriver to the fitting part of the drive shaft end that appears on the outside of the drive body and rotating it, the drive can be adjusted. The height of the elevating screw shaft can be adjusted up and down via a rotating wheel meshed with a bevel gear of the shaft, and a protrusion protruding into the opening of the drive body is provided in a vertical groove formed on the outside of the elevating screw shaft. Since the parts are slidably fitted together, it is possible to completely prevent the lifting screw shaft from rotating with the rotation of the rotation wheel, and to perform smooth and reliable lifting adjustment of the lifting screw shaft. Further, a rotating wheel is installed inside the drive body so as to be able to rotate in a fixed position within a horizontal plane, and an opening is provided in which the lifting screw shaft is screwed into a screw hole formed in the center of the rotating wheel and which passes through the upper and lower sides of the center of the drive body. Since the vertical height of the drive body can be set small, the device can be made more compact.Moreover, the stroke length of the height adjustment by vertical movement of the lifting screw shaft can be lengthened, making the height adjustment operation easier. is simple and can reduce costs.
